Aorsi

The Aorsi were an Iranian people of the Sarmatian group. The Aorsi and the Siraces migrated from Central Asia to the north and west of the Caspian Sea during the late 5th century BC, and they traded with India and Babylonia. In 49 AD, the Aorsi allied with the Roman Empire against the Siraces, and the Siraces were weakened as the Aorsi rose in strength. The Aorsi were one of the ancestors of the Alans.
